Intent. setdata (URI. parse ("Tel:" + mobile ));

Startactivity (intent );

Edittext mobiletext = (edittext) findviewbyid (R. Id. Mobile );

Edittext contenttext = (edittext) findviewbyid (R. Id. content );

String mobile = mobiletext. gettext (). tostring ();

String content = contenttext. gettext (). tostring ();

Smsmanager = smsmanager. getdefault ();

Arraylist <string> texts = smsmanager. dividemessage (content); // split the SMS

For (string text: texts ){

Smsmanager. sendtextmessage (mobile, null, text, null, null );

Public void onreceive (context, intent)

{

 

If ("android. provider. telephony. sms_received"

. Equals (intent. getaction ()))

{

String phonenumber = NULL;

String message = NULL;

// Receives data transmitted by SMS.

Bundle bundle = intent. getextras ();

// Determine whether data exists

If (bundle! = NULL)

{

// All received SMS messages can be obtained through PDUS.

Object [] objarray = (object []) bundle. Get ("PDUS ");

/* Construct the SMS object array and create the array size based on the length of the received object */

Smsmessage [] messages = new smsmessage [objarray. Length];

For (INT I = 0; I <objarray. length; I ++)

{

Messages [I] = smsmessage

. Createfrompdu (byte []) objarray [I]);

}

 

For (smsmessage currentmessage: messages)

{

Phonenumber = currentmessage. getdisplayoriginatingaddress ();

Message = currentmessage. getdisplaymessagebody ();

}

}

Toast. maketext (context, "Number =" + phonenumber + "MSG =" + message, Toast. length_long). Show ();

}
